Long, bezel-less, with great camera and highest performance
Samsung has recently officially presented its long-awaited flagship smartphones Galaxy S8 and Galaxy S8 +. Despite major setbacks in the recent past, Samsung's flagship devices not only continue to be the main competitor Apple iPhones but they are also some of the most technically advanced Android smartphones. Compared to the previous (seventh) generation, a lot has changed here, from the design in general to the arrangement of individual elements in particular, not to mention the improved hardware and updated software stuffing. Not all changes are for the better, but there are so many of them that we can say that Samsung has decided to start from scratch. It is worth noting that, to the delight of many, the difference between the Galaxy S8 and Galaxy S8 + models is only in size, almost everything else is the same. There are no various modifications with a variable amount of built-in memory or RAM, different performance, the presence or absence of certain elements. The user does not need to bother with the choice, it is enough just to decide on the preferred dimensions of the device. The technical characteristics of both models are almost identical, with their listing we will begin this review, choosing the Galaxy S8 + model as a sample.

Contents of delivery
Samsung Galaxy S8 + received a stylishly designed matte black cardboard box with a laconic design. The lid cannot be removed completely, it leans back like a casket. Contents are neatly packaged in separate cells.
The set, in the best traditions of Samsung, turned out to be extensive. The smartphone comes with a connecting USB cable Type-C, network adapter with variable output current and voltage 5/9 V 1.67 / 2 A, key unusual shape for card extraction, Micro-USB to USB Type-C adapter, second USB to USB Type-C adapter.
The company also included high-quality wired double-driver AKG stereo headphones with a set of interchangeable in-ear pads.
Appearance and usability
The design of the Samsung Galaxy S8 / S8 + turned out to be unusual and attractive. The streamlined body is completely made of metal and glass, there is no plastic here. A metal frame rounded on all sides, symmetrically tapering at the sides and expanding at the top and bottom ends, connects the two glass panels - the front and the back. The cover is Gorilla Glass 5, the glasses have noticeable curvatures on the sides. The bezel in the front plane of the screen is completely hidden behind the bend of the glass, so here we can talk about a truly bezel-less version.
The case of the Samsung Galaxy S8 + is absolutely symmetrical, the back side is also completely covered with Gorilla Glass 5 with curved edges. The edges of the glasses are rounded so strongly that they almost seamlessly (not counting the frames) merge into one another, creating a finished shape without a single sharp corner and straight edge. For this form, Samsung marketers have dubbed their new brainchild “smartphone without borders”.
Samsung Galaxy S8 + looks very attractive. And although such a design may seem too "licked" and "pampered", but such are the modern realities, the absolute majority of users liked it.
Due to the unusual aspect ratio of the display (not 16: 9, but 18.5: 9), the case turned out to be very elongated in height. At the same time, the absence of a frame on the sides of the screen in the front plane made it possible to make the body so narrow that it is quite comfortable to hold it in the hand even with a screen diagonal of 6.2 inches. True, the device is quite slippery due to its glass panels, smooth frame and streamlined shape.

The curved edges of the front glass work in conjunction with the corresponding software in the same way as in previous models of the series Galaxy Edge... A complete set of elements can be found above the screen, including an LED event indicator and even an iris scanner.
The scanner works tolerably, but the very process of setting the blocking and constant recognition is quite tedious, because this system works only under certain light conditions and at a certain distance from the eyes. It is much easier and faster to use the fingerprint scanner, although its location here causes some bewilderment.
There are no more control buttons under the screen, only on the screen itself. This is not typical for Samsung, its Galaxy smartphones there was always a hardware key on the front (in latest models- with an inscribed fingerprint sensor). Now its place was taken by a virtual button on the screen, but it is also not quite ordinary. In order for the static button, which is constantly highlighted in the Always On Display mode, not to cause pixel burnout, it was made movable. Thus, at first glance, the central button on the screen, which is static at first glance, is actually constantly shifting imperceptibly in different directions.
The fingerprint scanner has been moved to the back. At the same time, it is strongly displaced from the center to the right, so that it is inconvenient for a left-hander to reach with his finger. In addition, the tactile platform of the fingerprint sensor does not differ from the neighboring elements, it is difficult to feel it blindly, you need to get used to it. In general, this is, perhaps, the most unusual and inconvenient variant of the location of this element from all of us previously encountered, Samsung has again been too clever with a fingerprint sensor.
Next to the scanner, you can find a camera module with a flash, as well as a heart rate sensor familiar to Samsung smartphones. None of the elements stick out beyond the surface, so the smartphone is stable on the table, does not sway when you touch the screen. The flash is as bright as possible.
There are no complaints about the operation of the fingerprint scanner itself, it works quickly, clearly and accurately. But, as already mentioned, reaching for him, holding the smartphone in his left hand, is very inconvenient.
The slot for installing cards is located on the upper end. The cover of the removable slide, on which the cards are stacked, has a rubberized gasket, since the Samsung Galaxy S8 +, like the LG G6, complies with the IP68 protection category, that is, the case is completely protected from dust and can be immersed in water to a depth of 1.5 m for 30 minutes. However, the developers did not go further: the design here is not designed for harsh operating conditions, like the LG G6, so the hero of the review does not have a certification of the military standard.
It uses a standard hybrid slot that accepts either two Nano-SIM cards or one SIM and one microSD card. The slide is made of flexible plastic, the device itself reports on the need to tightly close the connector cover to protect it from water.
The volume control button has been moved to the left side face, here it is adjacent to separate key to call up the Bixby smart assistant, which allows you to access available services and applications using the touch screen, voice or text commands... The power key remained on the right side edge. The buttons are not very large, but the handling is quite comfortable, the keys are easily felt blindly.
All other interface elements are located at the bottom. A USB Type-C connector is installed here, which supports the connection of external devices in USB mode OTG, the main speaker is brought out here, as well as a 3.5 mm headphone jack and a spoken microphone hole. Surprisingly, the developers could not install any of the elements exactly, each of them turned out to be offset relative to the longitudinal axis of the end, which spoils the impression a little.
After examining the structure of the Galaxy S8 +, let's compare it with the previous model Galaxy S7 Edge. With the naked eye, you can see that the width of these smartphones is almost identical.
However, the Galaxy S8 + is equipped with a more elongated display with a custom aspect ratio, which allowed for more surface area under the screen. As a result, the 6.2-inch Galaxy S8 + sits in the palm of your hand just as comfortably as the 5.5-inch Galaxy S7 Edge.
In addition, the sides of the body of the review hero have become less slippery due to the increased width of the metal frame: the curved edges of the screen on the Galaxy S8 + have been reduced, the frame is now exactly in the middle between the front and rear panels. So, in general, the changes went to the novelty only for the benefit.
Samsung Galaxy S8 + is presented on the Russian market in three colors: black ("Black Diamond"), gray ("Mystical Amethyst") and gold ("Yellow Topaz").
Screen
The Samsung Galaxy S8 + features a Super AMOLED display with Corning Gorilla Glass 5 with highly rounded edges. The physical dimensions of the screen are approximately 70 × 142 mm with a diagonal of 6.2 inches, that is, the aspect ratio is 18.5: 9. The screen resolution is 2960 × 1440, the dot density is about 529 ppi. The corners of the screen, like the LG G6, are rounded, there are no side frames, as such, in the front plane of the screen, the upper and lower segments surrounding the screen are only about 8.5 mm high.

The brightness of the display can be adjusted manually or set automatic settings based on the operation of the ambient light sensor. HDR10 mode supported. The AnTuTu test diagnoses support for 10 simultaneous multitouch touches. There is a vision protection mode (preventing eye fatigue). In the Always-on mode, the off screen displays information about the current time and date, as well as about missed events.
In the screen settings section, you can choose the resolution and applications that should be used in full screen proportions. It seems that the developers first made a screen with an unusual aspect ratio, just so that it was "not like everyone else's", and then they added various "crutches" to the software so that the programs would work normally with such a screen.

A detailed examination using measuring instruments was carried out by the editor of the "Monitors" and "Projectors and TV" sections Alexey Kudryavtsev... Here is his expert opinion on the screen of the test sample.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than that of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left - Nexus 7, on the right - Samsung Galaxy S8 +, then they can be distinguished by their size):
The screen of the Samsung Galaxy S8 + is slightly darker (the brightness in the photos is 107 versus 115 for the Nexus 7) and does not have a pronounced shade. The doubling of reflected objects on the Samsung Galaxy S8 + screen is very weak, which indicates that there is no air gap between the layers of the screen. Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, screens without an air gap look better in conditions of intense ambient light, but their repair in case of cracked outer glass is much more expensive, since the entire screen has to be changed. The outer surface of the Samsung Galaxy S8 + screen has a special oleophobic (grease-repellent) coating (effective, better than that of the Nexus 7), so fingerprints are much easier to remove, and appear at a slower rate than in the case of regular glass.
When displaying a white field in full screen and when manual control the brightness of her maximum value was 370 cd / m² under normal conditions and rises to 580 cd / m² in very bright light. You also need to take into account the fact that in this case the smaller the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. For example, when displaying a white field on half of the screen and black on the other half, for the above conditions, we obtained values of 460 cd / m² and 725 cd / m². As a result, readability in the daytime in the sun should be at a good level. The minimum value is 1.6 cd / m². The reduced brightness level allows you to use the device without any problems even in complete darkness. Automatic brightness control works according to the light sensor (it is located to the left of the front speaker slot). The operation of this function depends on the position of the brightness adjustment slider, with which the user can try to set the desired brightness level in the current conditions. If the brightness slider is set to maximum in an office environment, then in complete darkness, the auto brightness function reduces the brightness to 6.4 cd / m² (a bit dark), in an office lit with artificial light (about 550 lx) sets it to 340 cd / m² (excessively bright) , in a very bright environment (equivalent to a bright day outdoors, but no direct sunlight - 20,000 lux or slightly more) increases to 545 cd / m² (sufficient). If, in complete darkness and in office conditions, set the brightness a little higher and lower, then the screen brightness for the three conditions mentioned above is as follows: 13, 180, 545 cd / m² (ideal combination). It turns out that the automatic brightness control function works adequately and to some extent allows the user to customize his work for individual requirements. At any brightness level, there is significant modulation with a frequency of about 60 or 240 Hz. The figure below shows the dependence of brightness (vertical axis) on time (horizontal axis) for several values of brightness adjustment:
It can be seen that at the maximum brightness and close to it, the modulation amplitude is not very large, as a result, there is no visible flicker. However, when the brightness decreases, modulation appears with a large relative amplitude, its presence can already be seen in the test for the presence of a stroboscopic effect or simply with rapid eye movement. Depending on individual sensitivity, such flickering can cause increased fatigue.
This screen uses a Super AMOLED matrix - an active matrix on organic light-emitting diodes. A full color image is created with subpixels of three colors - red (R), green (G) and blue (B), but there are twice as many green subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a micrograph:
For comparison, you can see the gallery of photomicrographs of screens used in mobile technology.
In the fragment above, you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), while repeating these fragments, you can lay out the entire screen without gaps and overlaps. For such matrices, Samsung has introduced the name PenTile RGBG. The manufacturer considers the screen resolution for green subpixels, for the other two it will be two times lower. The location and shape of the subpixels in this variant is close to the case of the Samsung Galaxy S4 screen and some other newer Samsung devices (and not only) with AMOLED screens. This PenTile RGBG variant is better than the old one with red squares, blue rectangles and green subpixel stripes. Nevertheless, some uneven contrast borders and other artifacts are still present. However, due to the very high resolution, they only have a minimal effect on image quality.
The screen has excellent viewing angles. True, when deviated even at small angles, the white color alternately acquires a light blue-green and pinkish tint, but the black color remains simply black at any angle. It is so black that the contrast setting is not applicable in this case. For comparison, here are the photos on which the screens of the Samsung Galaxy S8 + (profile Basic) and the second comparison participant displayed the same images, while the brightness of the screens was initially set to about 200 cd / m2, and the color balance on the camera was forcibly switched to 6500 K.
White box:
Note the good uniformity of brightness and color tone white margin (except for a slight darkening and a change in shade towards the curved edges).
And the test picture (profile Basic):
The color rendition is good, the colors are moderately saturated, the color balance of the screens is slightly different. Recall that the photograph can not serve as a reliable source of information about the quality of color reproduction and is provided for a conditional visual illustration only. In particular, the pronounced reddish tint of white and gray fields present in the photographs of the Samsung Galaxy S8 + screen is visually absent when viewed from a perpendicular view, which is confirmed by hardware tests using a spectrophotometer. The reason is that the spectral sensitivity of the camera matrix does not exactly match this characteristic of human vision. Note that in this case the picture occupies in height (with this screen orientation) the entire area available for image display and goes over the curved edges of the screen, which leads to darkening and color distortion. Also, in the light, these areas almost always glare, which further interferes when viewing images displayed in full screen. And even the picture of films with an aspect ratio of 16: 9 goes over the folds, which greatly interferes with watching a movie.
The photo above was taken after selecting a profile Basic in the screen settings, there are four of them:
Profile Adaptive display differs in some kind of automatic adjustment of the color rendition to the type of the displayed image and the surrounding conditions:
Saturation and color contrast are greatly increased, looks terrible. What happens when you select the two remaining profiles is shown below.
AMOLED movie:
Saturation and color contrast are also increased, but not as much.
Photo AMOLED:
Saturation is slightly lower, but color contrast is slightly higher than in the case AMOLED movie.
Now at an angle of approximately 45 degrees to the plane and to the side of the screen (profile Basic).
White box:
The brightness at an angle on both screens has noticeably decreased (to avoid strong darkening, the shutter speed is increased compared to previous photos), but in the case of Samsung, the drop in brightness is much less pronounced. As a result, with formally the same brightness screen samsung The Galaxy S8 + looks much brighter visually (compared to LCD screens), as the screen of a mobile device often has to be viewed from at least a slight angle.
And the test picture:
It can be seen that the colors have not changed much on both screens and the brightness of the Samsung smartphone is noticeably higher at an angle. The switching of the state of the matrix elements is performed almost instantly, but at the turn-on front there may be a step with a width of about 17 ms (which corresponds to a screen refresh rate of 60 Hz). For example, this is how the dependence of brightness on time looks like when switching from black to white and vice versa:
In some conditions, the presence of such a step can lead to plumes trailing behind moving objects. However, dynamic scenes in films on OLED screens are distinguished by high definition and even some "jerky" movements.
The gamma curve plotted using 32 points with equal intervals in terms of the numerical value of the shade of gray showed that there was no significant blockage either in the highlights or in the shadows. The exponent of the approximating power function is 2.09, which is slightly less than the standard value of 2.2, while the real gamma curve deviates little from the power dependence:
Recall that in the case of OLED screens, the brightness of image fragments dynamically changes in accordance with the nature of the displayed image - it decreases for generally light images. As a result, the obtained dependence of brightness on the hue (gamma curve), most likely, does not correspond a little to the gamma curve of a static image, since the measurements were carried out with sequential output of shades of gray on almost the entire screen.
Color gamut in case of profile Adaptive display very wide:
In profile AMOLED movie coverage is a bit narrower:
When choosing a profile Photo AMOLED the coverage is compressed to the borders of Adobe RGB:
When choosing a profile Basic coverage is compressed to sRGB borders:
Without correction, the spectra of the components are very well separated:
In case of a profile Basic with maximum correction, the color components are already noticeably mixed with each other:
Note that normal sRGB-optimized images appear unnaturally saturated on screens with wide color gamut without proper color correction. Hence the recommendation - in most cases, watching movies, photos and everything natural is better when choosing a profile. Basic, and only if the photo was taken on Adobe installation RGB, it makes sense to switch the profile to Photo AMOLED... Profile AMOLED movie despite the name, the least suitable for watching movies and anything else.
The grayscale balance is good. The color temperature is close to 6500 K, while this parameter does not change very much in a significant part of the gray scale, which improves the visual perception of the color balance. The deviation from the blackbody spectrum (ΔE) for most of the gray scale remains below 10 units, which is considered a good indicator for a consumer device:
(In most cases, the darkest areas of the gray scale can be ignored, since the color balance there does not really matter, and the error in measuring color characteristics at low brightness is large.)
For some reason, only when choosing a profile Adaptive display it becomes possible to adjust the color balance with three adjustments of the intensity of the primary colors, but due to the too wide color gamut, it is in this profile that it makes no sense to correct the balance.
Let's summarize. The screen has a very high maximum brightness and has excellent anti-reflective properties, so the device can be used outdoors without any problems, even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable value. It is permissible to use the mode with automatic brightness adjustment, which works adequately. The advantages of the screen include an effective oleophobic coating, as well as a color gamut close to sRGB and a good color balance. At the same time, let's recall the general advantages of OLED screens: true black color (if nothing is reflected in the screen), noticeably less than that of an LCD, the drop in image brightness when viewed from an angle. The disadvantages include modulation of the screen brightness. Users who are particularly sensitive to flicker may experience increased fatigue due to this. However, the overall quality of the screen is very high. Separately, we note that from the point of view of image quality, curled edges only harm, since this design find introduces very noticeable color tone distortions and reduces brightness at the edges of the picture, and in ambient light conditions leads to inevitable glare at least along one long side of the screen.
Camera
The front 8-megapixel camera does not receive its own flash, but it has a fast f / 1.7 lens and even supports intelligent autofocus with face detection. As front flash you can use the "fill" bright backlight of the screen right at the moment of shooting. Naturally, there is a mode for retouching selfie photos. The front camera shoots well for its level, there are no particular complaints about detail and sharpness, but it's hard to say that this camera is in some way better than analogues from Huawei, for example. Not bad, but nothing more.

The main camera uses a 12-megapixel sensor with a pixel size of 1.4 microns, as well as a fast f / 1.7 lens, OIS and Dual Pixel technology, which is designed to provide fast enough autofocusing to capture even the sharpest movements in low light conditions. There is a very bright LED flash.
Shoots the camera in automatic or manual mode... In manual mode, you can adjust shutter speed (1/24000 to 10 s), sensitivity (up to ISO 800), white balance and exposure compensation. There is the possibility of retouching images, support for HDR auto and a selective focus mode to change the depth of field on the finished image. The camera is also connected to the intelligent assistant Bixby, which must recognize objects of shooting, find places and translate texts from the screen.
Using the Camera2 API, you can transfer camera control to third-party applications. It is also possible to save images in RAW.

The camera can shoot video in 4K resolution (3840 × 2160), but only at 30 fps, and 60 fps is available only in Full HD (1920 × 1080). There is also a shooting mode at an intermediate resolution of 2560 × 1440, also at 30 fps. There's an optical image stabilization feature that really makes handheld shooting on the go extremely smooth. In any of the resolutions, the camera copes very well with video shooting: sharpness, color rendition and detail are normal, there is enough brightness, artifacts and slowdowns are out of the question. There are no complaints about sound recording either: the sensitivity of the microphones is high, the sound is clear, loud, the noise reduction system adequately copes with the wind noise.

Samsung continues to improve the quality of its cameras. The megapixel race, fortunately, has been forgotten, and now the manufacturer pays more attention to detail. Even in difficult scenes, the camera does not forget about small details, so the images look good even in low light conditions. Soapiness is gradually fading away, which means that the algorithms of the program have improved. The program has practically ceased to "eat" the details, and sharping is almost invisible. Of course, if you look closely, you can find both, but this is nit-picking.
A lab test confirms that the camera has remained virtually unchanged from the previous generation. However, there are differences, they just lie in the little things that are difficult to reflect on the stand. For those who like to tinker with photo processing, the manufacturer has made a very good RAW, which in some situations really allows you to get a result better than an intra-camera JPEG.
In general, the camera turned out to be quite flagship and will perfectly cope with many different scenes.
Telephone part and communications
The communication capabilities of the Samsung Galaxy S8 + include support for the advanced LTE Cat.16 technology, all three LTE FDD frequency bands of interest to us (Band 3, 7, 20) are supported, and there is also support for four TDD LTE bands (Band 38-41). Supports two Wi-Fi bands (2.4 and 5 GHz), there is Bluetooth 5.0 LE, you can organize a wireless access point via Wi-Fi or Bluetooth channels. The developers claim that thanks to support for Wi-Fi 1204-QAM and LTE Cat.16 standards, the download speed compared to previous flagships Samsung Galaxy S7 / S7 edge is increased by 20% both over Wi-Fi and over the mobile Internet. The device behaves confidently in the city limits of the Moscow region, the quality of signal reception raises no objections, the device demonstrates high speeds in the usual testing places, quickly restores the connection after a break.
The device has an NFC module, but it does not support electronic travel cards. The USB Type-C connector supports connecting external devices in USB OTG mode, the corresponding adapter is included in the accessory kit. The data transfer rate between a computer and a smartphone via a cable connected in the case of a PC to the USB 3.1 Type-C ports is about 26 MB / s.
The navigation module works with GPS (with A-GPS), with the domestic Glonass and with the Chinese Beidou. The first satellites during a cold start are detected within the first seconds, the positioning clarity is maximum. There is a built-in magnetic compass.

The phone application supports Smart Dial, that is, when dialing a phone number, a search is immediately carried out by the first letters in contacts. In the conversational dynamics, the voice of a familiar interlocutor is well recognizable, there is no extraneous noise, the sound is natural, clear, the volume reserve is sufficient. The power of the vibrating alert is much higher than the average level; its intensity can be changed manually.

Software and multimedia
As a software platform, the Samsung Galaxy S8 + uses Android OS version 7.0 Nougat with its own proprietary shell. There is a convenient ability to quickly transfer all data from your old smartphone to new samsung Galaxy S8 or S8 + using the included OTG adapter.
First of all, it should be noted that the enlarged display with a changed aspect ratio and high resolution provides more space for any information, text or graphics, so a lot of attention has been paid to the dual-window mode. Not every application here can be made to work in a small window; for this, each has a corresponding icon displayed in the menu of the last opened programs. That is, you first need to start and minimize the application in order to understand whether it has the ability to work in two-window mode, and then find the second one. Not a very simple and intuitive option, but you can get used to it. In addition, these windows can be resized. There is also the possibility of reducing the entire working area of the screen for ease of control with one hand. We cannot say that this functionality is convenient in practice, since all elements on the screen become too small, especially the buttons of the virtual keyboard, but there is such a possibility.

Due to the non-standard aspect ratio of the screen, the video in the player is displayed with black bars on the sides, but using scaling, the image can be stretched to the very edges of the screen. Some games report possible display issues, but overall we have not encountered any unsolvable issues.
Another feature of the Samsung Galaxy S8 + screen is the ability to use its curved sides, available for interaction with fingers due to the lack of frames. There is nothing new here: as before, an illuminated virtual strip can be displayed on the side of the screen, when pressed, a menu is opened that is responsible for quick contacts and instant access to the most used applications. Also here it becomes possible to select and save any part of the screen with further text recognition.

But of course, the main feature of the software of the new Korean smartphones was the emergence of Samsung's voice assistant - Bixby, which is a direct competitor to both Siri and Google Assistant, which, by the way, remained in place. As conceived by the developers, Bixby will be able not only to answer questions by collecting information on the Web, but also to identify a product using a camera and search for it on Amazon, translate texts in real time, and recognize landmarks. But the functions that will allow you to fully control the smartphone through voice commands are not yet available and will appear later.
 |
 |
 |
 |
As already mentioned, the smartphone's camera is connected to the Bixby intelligent assistant, which is supposed to recognize objects of shooting, find places and translate texts from the screen. True, in practice, for the Russian realities, all this is still difficult for him. Even if the main language of the device is Russian, the program will persistently offer to translate from any other language, but not from Russian. The assistant also does not know everything yet. At the same time, there were no problems with the translation from English into Russian.

There are very few additional programs, and those that exist are represented mainly by a set of Microsoft applications. Of particular note is Game Launcher, a handy game aggregator that automatically collects all installed game applications in one place, and also provides additional functions related to this. For example, it is possible to start recording the gameplay from the screen right during the game, with its further broadcast on the network. You can also use Game Launcher to improve system performance when launching selected games to enhance your gaming experience.

To listen to music, only a regular Google Play Music player is provided, supplemented by a powerful set of manual settings and equalizer presets, as well as Adapt sound technology for headphones. The set with the smartphone comes with two-driver AKG headphones with a very good sound quality for their level. But if everything is fine with the sound in the headphones, then the main speaker of the smartphone is not so impressive. It produces a rather monotonous and flat sound, without noticeable depth and saturation, although there are no complaints about the purity and volume reserve.

Performance
The hardware platform of the Samsung Galaxy S8 + is built on the Samsung Exynos 8895 Octa SoC with 8 cores in two clusters: 4 Exynos M1 cores up to 2.3 GHz and 4 ARM Cortex-A53 cores up to 1.7 GHz. This SoC is made using the latest 10nm process technology. Responsible for graphics processing is the Mali-G71 video accelerator with support for the Vulkan graphics API. The amount of RAM is 4 GB, and the internal memory is 64 GB, of which about 1.6 GB of RAM and 52.5 GB of ROM are initially free.
It should be noted that traditionally for Samsung Galaxy devices can be based on different SoCs: in this case, it is Qualcomm Snapdragon 835 or Exynos 8895. As always, the question of supply of this or that modification will depend on the region. The smartphone we received for tests ran on the Samsung Exynos 8895 platform.

According to the results of all SoC tests, without exception, Samsung Exynos 8895 showed the maximum results, it is the most powerful mobile platform at the moment of all we tested. Accordingly, the Samsung Galaxy S8 + is one of the most powerful smartphones available today and has a significant headroom for future updates. The smartphone confidently copes with any tasks in real scenarios, and thanks to the powerful video accelerator, it behaves perfectly even in the most demanding games. These videos of the gameplay in Modern Combat 5 and in Mortal Kombat X were recorded by the built-in means of the smartphone itself using the Game Launcher application.
Benchmarking AnTuTu and GeekBench:
All the results obtained by us when testing the smartphone in the most recent versions of popular benchmarks, we have summarized in tables for convenience. Several other devices from various segments are usually added to the table, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within the framework of one comparison, it is impossible to present the results from different versions of benchmarks, therefore, many worthy and relevant models remain "behind the scenes" - due to the fact that they once passed the "obstacle course" on previous versions of test programs.

Browser cross-platform tests:
As for benchmarks for evaluating the speed of the javascript engine, you should always make allowances for the fact that the results in them significantly depend on the browser in which they are launched, so that the comparison can be truly correct only on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

Testing has traditionally been conducted at typical power consumption levels without using power saving features. In the settings of the Samsung Galaxy S8 +, you can find operating modes from high-performance to economy, the choice of which will affect a lot, right down to the brightness and even the screen resolution.
Continuous reading in the Moon + Reader program (with a standard, light theme) at the minimum comfortable brightness level (the brightness was set to 100 cd / m2) with auto scrolling lasted 21.5 hours until the battery was fully discharged, and with continuous high quality video viewing (720p ) with the same brightness level via a home Wi-Fi network, the device operates up to 14.5 hours. In 3D games mode, the smartphone can work for more than 5 hours.
The smartphone should support fast charging, but we were not able to test this, since at the time of writing this review, the test device did not come with an AC adapter. However, from a conventional charger (5 V 2 A), the device charges quite quickly, within about an hour and a half with a current of 1.75 A at a voltage of 5 V. Wireless charging is also supported (WPC and PMA).
Outcome
The prices for the Russian market are as follows: On April 28, the Galaxy S8 and S8 + smartphones went on sale in Russia at a suggested retail price of 54,990 and 59,990, respectively. It is not entirely clear why the difference in the cost of devices of the same functionality with a slight difference only in the size of the display and the battery is as much as 5 thousand. Be that as it may, in the case of the Samsung Galaxy S8 + for 60 thousand, the manufacturer offers one of the best smartphones in many respects, including the quality of the camera, the performance of the hardware platform and very advanced communication capabilities, in an attractive and very unusual case, as well as with a lot of additional functions, many of which, however, were available in the previous models of the series.
At the same time, it cannot be said that the smartphone has become some kind of breakthrough, a new word in the creation of mobile devices and is completely devoid of disadvantages. A single main camera, although it is one of the best on the market, still looks rather strange against the background of the general movement towards increasing the number of modules. Also, one cannot praise the sound of the main speaker: in terms of sound, the device is clearly inferior to the flagship smartphones Apple and Huawei. The decision to move the fingerprint scanner to the back, and even to such an unfortunate location, was also highly questionable. Well, one cannot but recall the recent problems with the ignition of the batteries of Samsung mobile devices, against the background of which users may now be wary of paying a very high price, which the manufacturer asked for its mobile novelties, right away. And nevertheless, interest in the flagship devices of the Korean company has not weakened, it can be seen. Even those who were not going to shell out 60 thousand rubles for a smartphone are now eagerly discussing its capabilities on the Internet. However, something in the testing process remained undisclosed for us as well, since we did not have the final commercial sample in our hands. Most likely, we are still waiting, at least, a meeting with the brought to mind Bixby assistant, as well as with camera firmware updates, which may well expand its already remarkable capabilities.
In conclusion, we suggest watching our video review of the Samsung Galaxy S8 + smartphone:

Samsung Galaxy S8 design
Beautiful. Wow effect achieved. There are no side frames, the display goes to infinity, which became one of the leitmotifs of the official presentation of the Galaxy S8. A small frame remained at the top - it was necessary to place a speaker and two cameras somewhere, one for selfies, the other for scanning the retina. The bottom frame also remains, although there are no vital elements on it.
The Home button is hidden under the screen. The fingerprint scanner has moved to back cover and is located next to the main camera. We also left the 3.5 headphone jack, for which special thanks. The phone comes with AKG headphones, developed in collaboration with Harman Kardon, now owned by Samsung.
Galaxy S8 specifications: battery
This aspect of the technical characteristics of the Galaxy S8 will not be criticized only by the lazy, but we will not do it. Yes, the battery is only 3,000mAh for the S8 and 500mAh more for the S8 +, but fans of the brand have long been accustomed to the fact that the Galaxy flagship can barely make it into the evening. Nothing will change in 2017 either.The 10 nm chipset manufacturing process will help to save a little charge, so you shouldn't worry too much about the shortage of battery capacity.
Against the background of other flagships of spring 2017 Galaxy years The S8 looks fine. All leading manufacturers in pursuit of the flagship design sacrifice the battery and proudly say that the tube will last one day of light.
If for you the status is not in the first place (after all, the flagships buy precisely for this - to emphasize their status), but its practicality, it is better to buy, say, one that breaks all records in the rating of autonomy. Galaxy S8 and shouldn't work all day. His task is to shine!
Galaxy S8 display
The screen diagonal of 5.8 in the Galaxy S8 and 6.2 in the Galaxy S8 + were counted together with the curved part, so in reality the display is slightly smaller - about 5.6 and 5.9 inches. But with the resolution everything is correct - QHD +, that is, 1440 x 2960 pixels. The extra 400 pixels made the screen look longer. The aspect ratio has also changed - now 18.5: 9. The matrix is still the same - Super AMOLED. Pixel density 571 and 529.
The Galaxy S8 display supports HDR 10 technology, but does not support Dolby Vision. There is also no fantastic 4K resolution, as in Sony Xperia XZ Premium, but this can hardly be called a disadvantage. On screens with a diagonal of 5-6 inches, such innovations are used exclusively for marketing purposes, there is no real benefit from them.
Samsung Galaxy S8: hardware specifications
There are many innovations in the iron part, and much more useful than HDR10 technology on a tiny screen. Our Samsung Galaxy S8 will be sold with the Exynos 8895 chipset. We wrote about this chipset in detail and laid it out, so today we will focus on the key points.
The Exynos 8895 is built on a 10nm process technology. This ensures that the battery consumption is reduced while the operating speed is increased. The presentation officially announced that the computing power of the CPU ( CPU) will increase by 10%, the speed of the graphics adapter - by 21%. The numbers reflect the growth in performance of the Galaxy S8 over its predecessor, the Galaxy S7.

Is it worth worrying that the European market will not get Galaxy version S8 on Qualcomm Snapdragon 835? Perhaps not worth it. Yes, we know, many ordered S7 from the States, only to get an option on the SD820. Is this justified? Only from the point of view of a gamer, and even then ... doubtful. The Adreno 530 graphics adapter was faster than the Mali-T880 MP12, and the rest of the Exynos processor was better.
The Galaxy S8 is based on the even more powerful Exynos 8895, which in the first synthetic tests was in no way inferior to the Snapdragon 835. It was also ahead of the Kirin 960 installed in the. You don't need to remember about the 821 Dragon - they will lose very much to the new Samsung platform.
The only competitor to the Galaxy S8 in terms of performance may be, but this is unlikely to happen. The Japanese are leading in technology, but they manage to make relatively slow phones year after year. With top-end hardware, their flagships regularly fall short of direct competitors in all synthetic tests, and if nothing changes, the Galaxy S8 will become the fastest Android smartphone and will hold the lead until the autumn flagships are released.
And to end the conversation about the technical characteristics of the Galaxy S8, let's say that the phone received 4 GB of RAM and 64 internal memory... There is a microSD slot for expanding storage up to 256 GB.
Galaxy S8 camera
Specifications Galaxy cameras The S8 has barely changed. The phone received the same 12 megapixel module as its predecessor. At the presentation, we were told that to improve the quality of images, new technology multi-processing, which makes several additional frames. These shots are then combined with the user-captured photo, resulting in the perfect (as far as possible) shot - with killer detail, clarity, and color saturation.
In fact, there is nothing revolutionary about this technology. It works in HDR + mode on a similar principle, and this camera is recognized by experts as one of the best on the market. Something similar is offered by Sony, albeit in a slightly different context. The Xperia XZ Premium will take 4 preview photos before the camera launches (when motion is detected), and the user can choose the best option from these frames.
The advantage Xperia cameras XZ Premium is a unique Exmor RS sensor with its own RAM module. Thanks to the built-in RAM, the Xperia XZ Premium will be able to shoot super slow-mo at a frequency of 960 frames per second (but there is a minus - the shooting duration is limited to 0.18 seconds). The Galaxy S8 promised super slow-motion at fps, but not a word was said at the presentation.
To summarize the above, there is no real difference between the Galaxy S8 camera and the S7 camera. On the one hand, this is not bad - the Seventh Galactic took gorgeous photos. But on the other hand ... competitors are actively working to improve cameras. Take for example, or the LG G6 with a dual module and wide-angle lens. At this rate, the Galaxy S8 may fall out of the final ratings of the best smartphone cameras by the end of 2017 ...
Interfaces and software
The little things are very short - the Galaxy S8 supports wireless and fast charging. USB Type-C v.3.1 interface, wireless and fast charging, the headphone jack remained in its rightful place. Android ... no, no longer Marshmallow, but a real one Android 7.0 Nougat from the box!
